SAD-IRON.

SPECIFICATON forming part of Letters Patent No. 686,612, dated November 12, 1901.

Application filed May 9, 1901. Serial No. 59,513. (No model.)

To all whom it may concern:

Be it known that I,WILLIAM E. HoYT, a citizen of the United States,residin g at New York, in the county of New York and State of New York, have invented certain new anduseful Improvements in Sad-Irons, of which the following is a specification.

This invention relates to improvements in sad-ironshaving a combustion-chamber incorporated within itself wherein by the use of charcoal as 'fuel the iron may be kept at a constant and uniform heat; and one of the objects of my invention is to provide means whereby a regulated quantity of air may be admitted to the combustion-chamber and distributed more uniformly than heretofore to the fuel, causing a more perfect combustion and greater heat.

Another object of my invention is to provide a sad-iron which will be thoroughly efficient and practical, which can be produced at a moderate cost, and which will embody a iiuting device which will not render the iron cumbersome or inconvenient to handle and which flnting device will be thoroughly practical.

To attain the desired objects, the invention consists of a sad-iron embodying novel features of construction and combination of parts substantially as disclosed herein.

Figure 1 represents a'longitudinal vertical sectional view of my invention, showing the door in elevated Vposition and the damper in the side open. Fig. 2 is a like sectional View, but showing the side damper closed and the inner wall broken away` to expose the damper and showing the door down in closed position. Fig. 3 is a transverse section on `the dotted line 3 3 of Fig. 2. Fig. 4 represents a perspective view of my sad-iron. Fig. 5 is a detail in perspective of the end gate or door of my improved iron; Fig. 6, a detail in ver-` tical cross-section of the upper part of said door, and Fig. 7 a perspective view of the iron turned on its side with-the uting devices applied in operative position to clearly show the manner of using for luting.

Like letters of reference indicate like parts throughout the several views of the drawings. A represents the body of the iron, which is of usual shape or form and is made hollow to form a chamber A', having at one end the guides formed by a single outer flange aat each side, against which is fitted and slides the door or gate B. The bottom of the cham. 55 ber is formed with the longitudinal ribs C and is provided with the sloping false bottom C', which acts to collect the air and guide it to the bottom of the iron and discharge it between the ribs. The latter act to hold the 6o fuel away from the bottom of the iron, thereby providing channels or conduits for the better conduct of the air all along the base of the fuel- The two sides of the iron have the air-holes d, through which the admission of airis regulated by the plates D, which have openings d2. The plates D D, on either side of the chamber of the iron, are connected by the bridge-bar E, which has a rod extension E', 7o passing out'through an opening inthe front of the iron and terminating with the knob e on the outside. The plates have longitudinal adjustment against the sides of the body A, whereby the openings in the plate may be brought into register with the openings in the sides of the iron-body, or may be made to completely close the openings, or'placed at any intermediate position to only partially close said openings. By this means the quan- 8o tity of air admission through the sides of the iron may be carefully regulated.

The top edges of the sides of the iron are reduced in thickness to form shoulders,(shown at 3, Fig. 3,) upon which rest the plates D D.

G is the top of the iron, having the chimney g for permitting the escape of the products of combustion. `This chimney has the damper G' to regulate the draft. `The opposite end of the top from said chimney has the stand- 9o ard G2, which serves as a post against which the door below is frictionally fastened and also as one of the supports of a handle H, the opposite end of said handle being supported by attachment to the wall of the chimney g. A heat-deiiector h is interposed between the top of the iron and the handle. The top G also has the under side ange g3, which fits inside of the walls of the body A near the top of said walls and is secured thereto by screws 10o t, thereby uniting the top and body pieces of the iron. This flange engages the inside upper edge of the damper-slides at the side of the iron and helps to hold them in place. The

flange is removed sufficiently to allow the passage and free action of the bridge-bar E, connecting the two slides, as shown at e3 in Figs. l and 2.

K is a sheet-metal lining which is secured by the same screws that join the top and bottom sections of the iron together. It is held away from the outer wall of the iron a distance equal to the thickness of the flange g3, thereby producing an air-passage around the combustion-chamber. The said lining does not reach clear to the bottom of the combustion-chamber, but stops above it a suitable distance to allow the discharge of air under it. By the construction just described the air entering through the openings in the sides of the iron is conducted down between the outer walls of the iron and the lining and is discharged at the base of the combustion-chamber.

The to-and-fro movement of the iron while in use will create a circulation of air through it if proper openings are provided, and it is apparent that the quantity of air taken in during a given time will depend (the conditions of openings being the same) on the rapidity with which the iron is moved. A rapid movement mayA cause an excess of air to be admitted, causing a too-rapid combustion. Vhere charcoal is used as a fuel better results are obtained if an ample supply of air is afforded to the whole body of fuel, and in order to thus supply the air, distributing it in a general way to the mass from the rear of the iron, I make the door or gate B hollow, the chamber thus formed having a iiatinside plate b, having a number of evenly-distributed openings h', and the outside wall of said chamber having the openings b2, which are closed by the sliding damper-plate b3, having the usual openings whereby the size of the air-inlets to said chamber may be regulated. By this means a regulated quantity of air may be admitted to the chamber in the door, and whatever quantity enters said chamber will be discharged evenly into the combustion-chamber of the iron through the equallyspaced openings in plate h.

I is a lock for holding the door at any desired height. It consists of a disk i, thicker on one side, seated in a socket in the door having a correspondinglysloping bottom. The disk is rotated by means of a stem having an outside ring for a handle. By turning the stem the disk is forced out against the standard Gr2 or withdrawn therefrom, as I the case may be.

I provide in connection with my iron fluting devices which consist of the separate handle j, to which is connected the curved flutingplate j", which operates in connection with the liuting-plate ,72, which plate L72 is secured to the side ot the iron, as shown in Fig. 7.

Having thus fully described my invention, what I claim as new, and wish to secure by Letters Patent of the United States, is

l. In a sad-iron, a hollow body having side and end openings and longitudinal inside bottom ribs, a pair of sliding dampers to regulate the air-passage through the sides of the iron, said dampers being controlled byasingle rod passing to the outside of the iron, a lining extending from above the side openings of the iron to near the bottom of said iron, a vertically-sliding gate to close the rear end opening to the iron, means for holding the gate in its vertically-adjusted position, said gate being hollow and having air-openings through its external wall, a damperplate to regulate the air-passage through said external openings, and the inner wall of said hollow gate having a plurality of openings evenly distributed over the said inner wall, all substantially as described and shown.

2. In a sad-iron, a hollow body having side openings for the admission of air and a shoulder under said openings, a top having a flange entering the body, damper-plates opposite the openings and between the flanges and the walls of the iron and resting on said shoulders, a bar connecting the opposite damperplates and arod attached to the bar and passing through the front of the iron to the exterior thereof, substantially as described and Shown.

3. In a sad-iron, a hollow body having side openingsforthe admission of air, andashoulder under said openings, a top havingatlange entering the body, damper-plates opposite the openin gs and between the flanges and the walls of the iron resting on said shoulders, a bar connecting the opposite damper-plates, a rod attached to the bar and passing through the front of the iron to the exterior thereof and a lining secured at its upper edges to the anges and extending inside of the iron to near the bottom of the latter, substantially as described and shown.

In witness whereof I have hereunto set my hand and seal, at New York, this 25th day of April, A. D. 1901.
